BensCustomCases has posted a review on the CaseBuy EZ PSU Tester 

About a month back, CaseBuy contacted me and asked if I would review a couple of their products. I had never heard of them before, but I'm always willing to review new gear, so I agreed. A couple of weeks later, a package arrived from CaseBuy with a some gear that could help complete the toolbox of the gadget hound. If you've ever encountered weird computer problems that you really can't expain as software related, there is a chance that you've got some funky stuff happening with your hardware and possibly PSU. You can do one of two things, swap it out blindly and hope for the best, or test it and determine if it in fact is faulty. That's where the EZ Power Supply Tester comes in.
